Obstruction Evaluation / Airport Airspace Analysis (OE/AAA)

In administering Title 14 of the Code of Federal Regulations
(14 CFR)
Part 77, the prime objectives of the FAA are to promote air safety
and the efficient use of the navigable airspace. To accomplish
this mission, aeronautical studies are conducted based on information
provided by proponents on an FAA Form 7460-1, Notice of Proposed
Construction or Alteration.

If your organization is planning to sponsor any construction
or alterations which may affect navigable airspace, you must file a Notice of Proposed Construction or
Alteration (FAA Form 7460-1)
either electronically via this website or manually with the FAA.

E-filing your proposal is preferred because
- It's the fastest, most accurate method to submit to the FAA and immediately assigns an aeronautical study number to your case.
- It establishes an electronic communications link with FAA and allows you to obtain project status and notifications directly from this site.
